QNam: only init channels when needed.

QNam: only init channels when needed.

Each channel will create a socket that will allocate memory for the
read and write buffers. QNam generaly inits 6 sockets for each
connection. That means that by default 12 such buffers are created.
This will instead initialize channels when they are needed.
